After that, choose the 'Print & Fax' option in the 'System Preferences' box. In the following box, click on the 'Add' icon on the bottom. The issue stems from Apple having recently revoked the digital certificate installed on HP's printers via XProtect. XProtect is a feature by which Apple can prevent Mac devices from running.
Introduction: How to Connect HP 4050N Using Linksys Switch to Mac OS X Snow Leopard
I have an HP LaserJet 4050N that I use for my small business. It has the JetDirect card installed into it so the printer can be connected to a network using ethernet. Now, I also need to share my internet connection with other computers that are not wireless. The solution was to install a LinkSys 5-port switch into the mix.
My setup is as follows: iMac is connected to the internet via Airport. Next, I have a small ethernet cable coming out of the ethernet port on the iMac and going into the uplink port on the LinkSys Switch. Next, I personally have one ethernet cable running from the LinkSys Switch to my computer in the garage and one ethernet cable running from the LinkSys Switch to the JetDirect card ethernet port on the HP LaserJet 4050 Printer. The LinkSys Switch will allow for 3 more connections should you need them. This is how the cabling should run, pretty simple.
Step 1: Start Internet Sharing
Now you need to get your Mac to see the HP LaserJet, so that it can print to it. First, you need to open 'System Preferences' and click on the 'Sharing' folder under 'Internet & Wireless.'
Next, you click on the check box for the 'Internet Sharing' service. Since I use Airport to connect to the internet, I am sharing my connection from Airport to Computers using Ethernet. Once you make these selections, a small dialog box will pop up and ask if you want to 'start' internet sharing. Click 'Start.'
Step 2: Setup the Ethernet Connection to LinkSys

Go back to 'System Preferences' and click on 'Network.' Your Network screen may not look exactly like mine, but should be close.
Click on the 'Ethernet' service on the left side of this window/screen. Make the following selections:
Configure IPv4: Manually
IP Address: 192.168.2.1
Subnet Mask: 255.255.255.0
Router: 192.168.2.1
Click Apply
At this time, open 'Network Utility' and check the 'Ethernet en0' interface. The IP Address should exactly the same as the IP address that you manually typed into the Network screen.
Step 3: Setup HP LaserJet I/O JetDirect Card on Printer
This is the tedious step, because it's not as friendly as Mac OS X. You will need to turn on the printer and press the 'Menu' button seven (7) times to access the EIO 2 JetDirect Menu.
Press the 'Item' button once to the right. It will say: CFG NETWORK=NO *
Press the 'Value' button once the right (+), then press the 'Select' button. It should say: CFG NETWORK=YES *
The attached video should help you configure the printer. Just make sure that you press 'Select' after each entry when putting the numbers into the menu. I set my printer to use an IP Address of: 192.168.2.10. The IP Byte is where you put in the IP Address Numbers. The SM bytes are the Subnet Mask numbers. The LG bytes have no effect here, so they are 0.0.0.1. The GW Bytes are the 'Gateway' bytes or server address, which is: 192.168.2.1.
Once you have set up your IP numbers, you're ready for the next step.

Step 4: Adding the HP LaserJet Printer to Your Printers
Open 'System Preferences' again and click on 'Print & Fax.' Now, you're going to add the HP LaserJet 4050 printer to your list of available printers.
Click the '+' button. The Add Printer Dialog Box will come up. The choices are: 'Default', 'Fax', 'IP', and 'Windows'
You want to select 'IP'
The Protocol should be 'HP Jetdirect - Socket'
The Address will be the IP address you gave the printer in the CFG screen of the printer. Again, I used 192.168.2.10 for my IP Address. So, in this Address Field, you will type in the number you gave your printer.
The Queue field is where you can Name your printer. I called mine HP LaserJet 4050
In the Name field, you use the same name as Queue. Mac os el capitan download free. Again, mine is called HP LaserJet 4050
Location: You can leave this blank, but I put the physical location of mine, which is right next to my iMac.
Print Using: HP LaserJet 4050 Series. This is where you select the printer driver. Click on the down arrow and select the HP LaserJet 4050 Series Software.
Backup devices for mac. Click 'Add' and you should see your HP Printer show up in your printer list.
Step 5: Print Something With Your Networked Printer
Open 'System Preferences' one more time and select 'Print & Fax'
Click once on your HP LaserJet 4050 to highlight it in Blue.
Double-click on the highlighted printer and it will open up the HP LaserJet 4050 Queue.
Click on 'Printer Setup' to see all kinds of information about your printer. Notice the URL Socket will show the IP address that you gave your printer.
Now click on the 'Printer' drop down menu and select 'Print Test Page'
It should connect to your printer and print the test page.
Congratulations, you're done!!!
Note: this should work with any networkable printer, not just the HP 4050.

Apple macOS X users with HP printers are left unable to print from their computers after Apple revoked a certificate that signed HP's print drivers.
The result was print drivers being mistaken on macOS X for malware, and user complaints springing up over the weekend.
Print drivers mistook for malware
As observed by BleepingComputer, when printing a document from a MacBook running macOS Catalina (10.15.7 (19H2)) to an HP printer, the job remains in print queue but does not complete. That's because the corresponding print driver is being mistaken as malware.
Reports of macOS users with HP printers experiencing the issue emerged on Apple, HP forums, and of course, Twitter.

The problem seems to impact both macOS Catalina (10.15) and Mojave (10.14) users with HP printers.
Furthermore, the print queue shows a mysterious 'Encryption credentials have expired' message.
The issue stems from Apple having recently revoked the digital certificate installed on HP's printers via XProtect.
XProtect is a feature by which Apple can prevent Mac devices from running certain applications it no longer deems trustworthy.
Apple does so by revoking the cryptographic code-signing certificates associated with these applications.
'There is no central database of certs cancelled by XProtect, there's one for each OS version it seems, and Catalina and Mojave were selected in particular. Apple chose to revoke the HP driver cert, or perhaps was asked to do so by HP,' explained The Register.
How to resolve the issue?
macOS X users can resolve the issue by following a series of steps outlined below.
The advice specifically applies to HP OfficeJet models with wireless printing and the printer's web interface enabled.
- Remove the /Library/Printers/hp folder to delete any old drivers that are being incorrectly flagged as malware
- Open System Preferences on your macOS X and navigate to the Printers & Scanners area.
- Double-click on the printer and then select 'Printer settings.' and then click 'Show Printer Web Page..'
Once on the printer's web page, follow the steps provided by HP's Knowledge Base to generate a new Self-Signed certificate for the device.
This generates a new certificate for your HP printer with 10-year validity. Ignore the 'Not Secure' warning; that is typical for self-signed certificates.
Now return to the Printers & Scanners area, right-click (Cmd+click) on your printer and select the 'Reset printing system..' option
This will uninstall and remove the printer from the list. Now click the '+' icon to re-add it.

You may also use the 'IP' option to add the printer by its IP address should the 'Bonjour' (AirPrint) connectivity fail.
You should now be able to print from applications such as your web browser and Preview seamlessly to your printer.
The 'Encryption credentials have expired' message should also no longer appear in your print queue.
While SSL certificate expiry dates and revocations are essential security features, these can become a hindrance in legitimate use cases if not planned properly by the industry players.
In Apple's case, revoking HP's certificates without a heads up left very many users without a means to print and having to deal with confusing 'malware' alerts.
Update, Oct 30th 2020:
Apple reached out to BleepingComputer to clarify that the revoked certificates were an action undertaken by HP:
'We unintentionally revoked credentials on some older versions of Mac drivers. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer,' said HP.
